- * There used to be a bug in the X server where it would rely on
- * out-of-bounds accesses when it was asked to composite with a
- * window as the source. It would create a pixman image pointing
- * to some bogus position in memory, but then set a clip region
- * to the position where the actual bits were.
- *
- * Due to a bug in old versions of pixman, where it would not clip
- * against the image bounds when a clip region was set, this would
- * actually work. So when the pixman bug was fixed, a workaround was
- * added to allow certain out-of-bound accesses. This function disabled
- * those workarounds.
- *
- * Since 0.21.2, pixman doesn't do these workarounds anymore, so now
- * this function is a no-op.

- * Manual (PDF 32000-1:2008 at the time of this writing).
- *
- * In the radial gradient problem we are given two circles (c₁,r₁) and
- * (c₂,r₂) that define the gradient itself.
- *
- * Mathematically the gradient can be defined as the family of circles
- *
- * ((1-t)·c₁ + t·(c₂), (1-t)·r₁ + t·r₂)
- *
- * excluding those circles whose radius would be < 0. When a point
- * belongs to more than one circle, the one with a bigger t is the only
- * one that contributes to its color. When a point does not belong
- * to any of the circles, it is transparent black, i.e. RGBA (0, 0, 0, 0).
- * Further limitations on the range of values for t are imposed when
- * the gradient is not repeated, namely t must belong to [0,1].
- *
- * The graphical result is the same as drawing the valid (radius > 0)
- * circles with increasing t in [-inf, +inf] (or in [0,1] if the gradient
- * is not repeated) using SOURCE operatior composition.

- * It looks like a cone pointing towards the viewer if the ending circle
- * is smaller than the starting one, a cone pointing inside the page if
- * the starting circle is the smaller one and like a cylinder if they
- * have the same radius.
- *
- * What we actually do is, given the point whose color we are interested
- * in, compute the t values for that point, solving for t in:
- *
- * length((1-t)·c₁ + t·(c₂) - p) = (1-t)·r₁ + t·r₂
- *
- * Let's rewrite it in a simpler way, by defining some auxiliary
- * variables:
- *
- * cd = c₂ - c₁
- * pd = p - c₁
- * dr = r₂ - r₁
- * lenght(t·cd - pd) = r₁ + t·dr
- *
- * which actually means
- *
- * hypot(t·cdx - pdx, t·cdy - pdy) = r₁ + t·dr
- *
- * or
- *
- * ⎷((t·cdx - pdx)² + (t·cdy - pdy)²) = r₁ + t·dr.
- *
- * If we impose (as stated earlier) that r₁ + t·dr >= 0, it becomes:
- *
- * (t·cdx - pdx)² + (t·cdy - pdy)² = (r₁ + t·dr)²
- *
- * where we can actually expand the squares and solve for t:
- *
- * t²cdx² - 2t·cdx·pdx + pdx² + t²cdy² - 2t·cdy·pdy + pdy² =
- * = r₁² + 2·r₁·t·dr + t²·dr²
- *
- * (cdx² + cdy² - dr²)t² - 2(cdx·pdx + cdy·pdy + r₁·dr)t +
- * (pdx² + pdy² - r₁²) = 0
- *
- * A = cdx² + cdy² - dr²
- * B = pdx·cdx + pdy·cdy + r₁·dr
- * C = pdx² + pdy² - r₁²
- * At² - 2Bt + C = 0
- *
- * The solutions (unless the equation degenerates because of A = 0) are:
- *
- * t = (B ± ⎷(B² - A·C)) / A
- *
- * The solution we are going to prefer is the bigger one, unless the
- * radius associated to it is negative (or it falls outside the valid t
- * range).
- *
- * Additional observations (useful for optimizations):
- * A does not depend on p
- *
- * A < 0 <=> one of the two circles completely contains the other one
- * <=> for every p, the radiuses associated with the two t solutions
- * have opposite sign

-.SH NAME
-__xservername__ - X11R7 X server
-.SH SYNOPSIS
-.B __xservername__
-.RI [\fB:\fP display ]
-.RI [ option
-.IR ... ]
-.SH DESCRIPTION
-.B __xservername__
-is a full featured X server that was originally designed for UNIX and
-UNIX-like operating systems running on Intel x86 hardware. It now runs
-on a wider range of hardware and OS platforms.
-.PP
-This work was derived by the X.Org Foundation from the XFree86 Project's
-.I "XFree86\ 4.4rc2"
-release.
-The XFree86 release was originally derived from
-.I "X386\ 1.2"
-by Thomas Roell which was contributed to X11R5 by Snitily Graphics
-Consulting Service.
-.SH PLATFORMS
-.PP
-.B __xservername__
-operates under a wide range of operating systems and hardware platforms.
-The Intel x86 (IA32) architecture is the most widely supported hardware
-platform. Other hardware platforms include Compaq Alpha, Intel IA64, AMD64,
-SPARC and PowerPC. The most widely supported operating systems are the
-free/OpenSource UNIX-like systems such as Linux, FreeBSD, NetBSD,
-OpenBSD, and Solaris. Commercial UNIX operating systems such as
-UnixWare are also supported. Other supported operating systems include
-GNU Hurd. Mac OS X is supported with the
-Xquartz(__appmansuffix__) X server. Win32/Cygwin is supported with the
-XWin(__appmansuffix__) X server.
-.PP
-.SH "NETWORK CONNECTIONS"
-.B __xservername__
-supports connections made using the following reliable
-byte-streams:
-.TP 4
-.I "Local"
-On most platforms, the "Local" connection type is a UNIX-domain socket.
-On some System V platforms, the "local" connection types also include
-STREAMS pipes, named pipes, and some other mechanisms.
-.TP 4
-.I TCP\/IP
-.B __xservername__
-listens on port
-.RI 6000+ n ,
-where
-.I n
-is the display number. This connection type can be disabled with the
-.B \-nolisten
-option (see the Xserver(1) man page for details).
-.SH "ENVIRONMENT VARIABLES"
-For operating systems that support local connections other than Unix
-Domain sockets (SVR3 and SVR4), there is a compiled-in list specifying
-the order in which local connections should be attempted. This list
-can be overridden by the
-.I XLOCAL
-environment variable described below. If the display name indicates a
-best-choice connection should be made (e.g.
-.BR :0.0 ),
-each connection mechanism is tried until a connection succeeds or no
-more mechanisms are available. Note: for these OSs, the Unix Domain
-socket connection is treated differently from the other local connection
-types. To use it the connection must be made to
-.BR unix:0.0 .
-.PP
-The
-.I XLOCAL
-environment variable should contain a list of one more
-more of the following:
-.PP
-.RS 8
-.nf
-NAMED
-PTS
-SCO
-ISC
-.fi
-.RE
-.PP
-which represent SVR4 Named Streams pipe, Old-style USL Streams pipe,
-SCO XSight Streams pipe, and ISC Streams pipe, respectively. You can
-select a single mechanism (e.g.
-.IR XLOCAL=NAMED ),
-or an ordered list (e.g. \fIXLOCAL="NAMED:PTS:SCO"\fP).
-his variable overrides the compiled-in defaults. For SVR4 it is
-recommended that
-.I NAMED
-be the first preference connection. The default setting is
-.IR PTS:NAMED:ISC:SCO .
-.PP
-To globally override the compiled-in defaults, you should define (and
-export if using
-.B sh
-or
-.BR ksh )
-.I XLOCAL
-globally. If you use startx(1) or xinit(1), the definition should be
-at the top of your
-.I .xinitrc
-file. If you use xdm(1), the definitions should be early on in the
-.I __projectroot__/lib/X11/xdm/Xsession
-script.
-.SH OPTIONS
-.B __xservername__
-supports several mechanisms for supplying/obtaining configuration and
-run-time parameters: command line options, environment variables, the
-__xconfigfile__(__filemansuffix__) configuration files, auto-detection, and
-fallback defaults. When the same information is supplied in more than
-one way, the highest precedence mechanism is used. The list of mechanisms
-is ordered from highest precedence to lowest. Note that not all parameters
-can be supplied via all methods. The available command line options
-and environment variables (and some defaults) are described here and in
-the Xserver(__appmansuffix__) manual page. Most configuration file
-parameters, with their defaults, are described in the
-__xconfigfile__(__filemansuffix__) manual page. Driver and module specific
-configuration parameters are described in the relevant driver or module
-manual page.
-.PP
-In addition to the normal server options described in the
-Xserver(__appmansuffix__) manual page,
-.B __xservername__
-accepts the following command line switches:
-.TP 8
-.BI vt XX
-.I XX
-specifies the Virtual Terminal device number which
-.B __xservername__
-will use. Without this option,
-.B __xservername__
-will pick the first available Virtual Terminal that it can locate. This
-option applies only to platforms that have virtual terminal support, such
-as Linux, BSD, OpenSolaris, SVR3, and SVR4.
-.TP
-.B \-allowMouseOpenFail
-Allow the server to start up even if the mouse device can't be opened
-or initialised. This is equivalent to the
-.B AllowMouseOpenFail
-__xconfigfile__(__filemansuffix__) file option.
-.TP 8
-.B \-allowNonLocalXvidtune
-Make the VidMode extension available to remote clients. This allows
-the xvidtune client to connect from another host. This is equivalent
-to the
-.B AllowNonLocalXvidtune
-__xconfigfile__(__filemansuffix__) file option. By default non-local
-connections are not allowed.
-.TP 8
-.BI \-bgamma " value"
-Set the blue gamma correction.
-.I value
-must be between 0.1 and 10.
-The default is 1.0. Not all drivers support this. See also the
-.BR \-gamma ,
-.BR \-rgamma ,
-and
-.B \-ggamma
-options.
-.TP 8
-.BI \-bpp " n"
-No longer supported. Use
-.B \-depth
-to set the color depth, and use
-.B \-fbbpp
-if you really need to force a non-default framebuffer (hardware) pixel
-format.
-.TP 8
-.BI \-config " file"
-Read the server configuration from
-.IR file .
-This option will work for any file when the server is run as root (i.e,
-with real-uid 0), or for files relative to a directory in the config
-search path for all other users.
-.TP 8
-.BI \-configdir " directory"
-Read the server configuration files from
-.IR directory .
-This option will work for any directory when the server is run as root
-(i.e, with real-uid 0), or for directories relative to a directory in the
-config directory search path for all other users.
-.TP 8
-.B \-configure
-When this option is specified, the
-.B __xservername__
-server loads all video driver modules, probes for available hardware,
-and writes out an initial __xconfigfile__(__filemansuffix__) file based on
-what was detected. This option currently has some problems on some
-platforms, but in most cases it is a good way to bootstrap the
-configuration process. This option is only available when the server
-is run as root (i.e, with real-uid 0).
-.TP 8
-.BI "\-crt /dev/tty" XX
-SCO only. This is the same as the
-.B vt
-option, and is provided for compatibility with the native SCO X server.
-.TP 8
-.BI \-depth " n"
-Sets the default color depth. Legal values are 1, 4, 8, 15, 16, and
-24. Not all drivers support all values.
-.TP 8
-.B \-disableVidMode
-Disable the parts of the VidMode extension (used by the xvidtune
-client) that can be used to change the video modes. This is equivalent
-to the
-.B DisableVidModeExtension
-__xconfigfile__(__filemansuffix__) file option.
-.TP 8
-.B \-fbbpp \fIn\fP
-Sets the number of framebuffer bits per pixel. You should only set this
-if you're sure it's necessary; normally the server can deduce the correct
-value from
-.B \-depth
-above. Useful if you want to run a depth 24 configuration with a 24
-bpp framebuffer rather than the (possibly default) 32 bpp framebuffer
-(or vice versa). Legal values are 1, 8, 16, 24, 32. Not all drivers
-support all values.
-.TP 8
-.B \-flipPixels
-Swap the default values for the black and white pixels.
-.TP 8
-.BI \-gamma " value"
-Set the gamma correction.
-.I value
-must be between 0.1 and 10. The default is 1.0. This value is applied
-equally to the R, G and B values. Those values can be set independently
-with the
-.BR \-rgamma ,
-.BR \-bgamma ,
-and
-.B \-ggamma
-options. Not all drivers support this.
-.TP 8
-.BI \-ggamma " value"
-Set the green gamma correction.
-.I value
-must be between 0.1 and 10. The default is 1.0. Not all drivers support
-this. See also the
-.BR \-gamma ,
-.BR \-rgamma ,
-and
-.B \-bgamma
-options.
-.TP 8
-.B \-ignoreABI
-The
-.B __xservername__
-server checks the ABI revision levels of each module that it loads. It
-will normally refuse to load modules with ABI revisions that are newer
-than the server's. This is because such modules might use interfaces
-that the server does not have. When this option is specified, mismatches
-like this are downgraded from fatal errors to warnings. This option
-should be used with care.
-.TP 8
-.B \-isolateDevice \fIbus\-id\fP
-Restrict device resets to the device at
-.IR bus\-id .
-The
-.I bus\-id
-string has the form
-.IB bustype : bus : device : function
-(e.g., \(oqPCI:1:0:0\(cq).
-At present, only isolation of PCI devices is supported; i.e., this option
-is ignored if
-.I bustype
-is anything other than \(oqPCI\(cq.
-.TP 8
-.B \-keeptty
-Prevent the server from detaching its initial controlling terminal.
-This option is only useful when debugging the server. Not all platforms
-support (or can use) this option.
-.TP 8
-.BI \-keyboard " keyboard-name"
-Use the __xconfigfile__(__filemansuffix__) file
-.B InputDevice
-section called
-.I keyboard-name
-as the core keyboard. This option is ignored when the
-.B Layout
-section specifies a core keyboard. In the absence of both a Layout
-section and this option, the first relevant
-.B InputDevice
-section is used for the core keyboard.
-.TP 8
-.BI \-layout " layout-name"
-Use the __xconfigfile__(__filemansuffix__) file
-.B Layout
-section called
-.IR layout-name .
-By default the first
-.B Layout
-section is used.
-.TP 8
-.BI \-logfile " filename"
-Use the file called
-.I filename
-as the
-.B __xservername__
-server log file. The default log file is
-.BI __logdir__/__xservername__. n .log
-on most platforms, where
-.I n
-is the display number of the
-.B __xservername__
-server. The default may be in a different directory on some platforms.
-This option is only available when the server is run as root (i.e, with
-real-uid 0).
-.TP 8
-.BR \-logverbose " [\fIn\fP]"
-Sets the verbosity level for information printed to the
-.B __xservername__
-server log file. If the
-.I n
-value isn't supplied, each occurrence of this option increments the log
-file verbosity level. When the
-.I n
-value is supplied, the log file verbosity level is set to that value.
-The default log file verbosity level is 3.
-.TP 8
-.BI \-modulepath " searchpath"
-Set the module search path to
-.IR searchpath .
-.I searchpath
-is a comma separated list of directories to search for
-.B __xservername__
-server modules. This option is only available when the server is run
-as root (i.e, with real-uid 0).
-.TP 8
-.B \-nosilk
-Disable Silken Mouse support.
-.TP 8
-.B \-pixmap24
-Set the internal pixmap format for depth 24 pixmaps to 24 bits per pixel.
-The default is usually 32 bits per pixel. There is normally little
-reason to use this option. Some client applications don't like this
-pixmap format, even though it is a perfectly legal format. This is
-equivalent to the
-.B Pixmap
-__xconfigfile__(__filemansuffix__) file option.
-.TP 8
-.B \-pixmap32
-Set the internal pixmap format for depth 24 pixmaps to 32 bits per pixel.
-This is usually the default. This is equivalent to the
-.B Pixmap
-__xconfigfile__(__filemansuffix__) file option.
-.TP 8
-.BI \-pointer " pointer-name"
-Use the __xconfigfile__(__filemansuffix__) file
-.B InputDevice
-section called
-.I pointer-name
-as the core pointer. This option is ignored when the
-.B Layout
-section specifies a core pointer. In the absence of both a Layout
-section and this option, the first relevant
-.B InputDevice
-section is used for the core pointer.
-.TP 8
-.B \-quiet
-Suppress most informational messages at startup. The verbosity level
-is set to zero.
-.TP 8
-.BI \-rgamma " value"
-Set the red gamma correction.
-.I value
-must be between 0.1 and 10. The default is 1.0. Not all drivers support
-this. See also the
-.BR \-gamma ,
-.BR \-bgamma ,
-and
-.B \-ggamma
-options.
-.TP 8
-.BI \-screen " screen-name"
-Use the __xconfigfile__(__filemansuffix__) file
-.B Screen
-section called
-.IR screen-name .
-By default the screens referenced by the default
-.B Layout
-section are used, or the first
-.B Screen
-section when there are no
-.B Layout
-sections.
-.TP 8
-.B \-showconfig
-This is the same as the
-.B \-version
-option, and is included for compatibility reasons. It may be removed
-in a future release, so the
-.B \-version
-option should be used instead.
-.TP 8
-.B \-showDefaultModulePath
-Print out the default module path the server was compiled with.
-.TP 8
-.B \-showDefaultLibPath
-Print out the path libraries should be installed to.
-.TP 8
-.B \-showopts
-For each driver module installed, print out the list of options and their
-argument types.
-.TP 8
-.BI \-weight " nnn"
-Set RGB weighting at 16 bpp. The default is 565. This applies only to
-those drivers which support 16 bpp.
-.TP 8
-.BR \-verbose " [\fIn\fP]"
-Sets the verbosity level for information printed on stderr. If the
-.I n
-value isn't supplied, each occurrence of this option increments the
-verbosity level. When the
-.I n
-value is supplied, the verbosity level is set to that value. The default
-verbosity level is 0.
-.TP 8
-.B \-version
-Print out the server version, patchlevel, release date, the operating
-system/platform it was built on, and whether it includes module loader
-support.
-.SH "KEYBOARD"
-.PP
-The
-.B __xservername__
-server is normally configured to recognize various special combinations
-of key presses that instruct the server to perform some action, rather
-than just sending the key press event to a client application. These actions
-depend on the XKB keymap loaded by a particular keyboard device and may or
-may not be available on a given configuration.
-.PP
-The following key combinations are commonly part of the default XKEYBOARD
-keymap.
-.TP 8
-.B Ctrl+Alt+Backspace
-Immediately kills the server -- no questions asked. It can be disabled by
-setting the
-.B DontZap
-__xconfigfile__(__filemansuffix__) file option to a TRUE value.
-.PP
-.RS 8
-It should be noted that zapping is triggered by the
-.B Terminate_Server
-action in the keyboard map. This action is not part of the default keymaps
-but can be enabled with the XKB option
-.B \*qterminate:ctrl_alt_bksp\*q.
-.RE
-.TP 8
-.B Ctrl+Alt+Keypad-Plus
-Change video mode to next one specified in the configuration file.
-This can be disabled with the
-.B DontZoom
-__xconfigfile__(__filemansuffix__) file option.
-.TP 8
-.B Ctrl+Alt+Keypad-Minus
-Change video mode to previous one specified in the configuration file.
-This can be disabled with the
-.B DontZoom
-__xconfigfile__(__filemansuffix__) file option.
-.TP 8
-.B Ctrl+Alt+F1...F12
-For systems with virtual terminal support, these keystroke
-combinations are used to switch to virtual terminals 1 through 12,
-respectively. This can be disabled with the
-.B DontVTSwitch
-__xconfigfile__(__filemansuffix__) file option.
-.SH CONFIGURATION
-.B __xservername__
-typically uses a configuration file called
-.B __xconfigfile__
-and configuration files with the suffix
-.I .conf
-in a directory called
-.B __xconfigdir__
-for its initial setup.
-Refer to the __xconfigfile__(__filemansuffix__) manual page for information
-about the format of this file.
-.PP
-.B __xservername__
-has a mechanism for automatically generating a built-in configuration
-at run-time when no
-.B __xconfigfile__
-file or
-.B __xconfigdir__
-files are present. The current version of this automatic configuration
-mechanism works in two ways.
-.PP
-The first is via enhancements that have made many components of the
-.B __xconfigfile__
-file optional. This means that information that can be probed or
-reasonably deduced doesn't need to be specified explicitly, greatly
-reducing the amount of built-in configuration information that needs to
-be generated at run-time.
-.PP
-The second is to have "safe" fallbacks for most configuration information.
-This maximises the likelihood that the
-.B __xservername__
-server will start up in some usable configuration even when information
-about the specific hardware is not available.
-.PP
-The automatic configuration support for __xservername__ is work in progress.
-It is currently aimed at the most popular hardware and software platforms
-supported by __xservername__. Enhancements are planned for future releases.
-.SH FILES
-The
-.B __xservername__
-server config files can be found in a range of locations. These are
-documented fully in the __xconfigfile__(__filemansuffix__) manual page. The
-most commonly used locations are shown here.

+.\" $XdotOrg: xserver/xorg/hw/xfree86/doc/man/Xorg.man.pre,v 1.3 2005/07/04 18:41:01 ajax Exp $ +.\" shorthand for double quote that works everywhere. +.ds q \N'34' +.TH __xservername__ __appmansuffix__ __vendorversion__ +.SH NAME +__xservername__ - X11R7 X server +.SH SYNOPSIS +.B __xservername__ +.RI [\fB:\fP display ] +.RI [ option +.IR ... ] +.SH DESCRIPTION +.B __xservername__ +is a full featured X server that was originally designed for UNIX and +UNIX-like operating systems running on Intel x86 hardware. It now runs +on a wider range of hardware and OS platforms. +.PP +This work was derived by the X.Org Foundation from the XFree86 Project's +.I "XFree86\ 4.4rc2" +release. +The XFree86 release was originally derived from +.I "X386\ 1.2" +by Thomas Roell which was contributed to X11R5 by Snitily Graphics +Consulting Service. +.SH PLATFORMS +.PP +.B __xservername__ +operates under a wide range of operating systems and hardware platforms. +The Intel x86 (IA32) architecture is the most widely supported hardware +platform. Other hardware platforms include Compaq Alpha, Intel IA64, AMD64, +SPARC and PowerPC. The most widely supported operating systems are the +free/OpenSource UNIX-like systems such as Linux, FreeBSD, NetBSD, +OpenBSD, and Solaris. Commercial UNIX operating systems such as +UnixWare are also supported. Other supported operating systems include +GNU Hurd. Mac OS X is supported with the +Xquartz(__appmansuffix__) X server. Win32/Cygwin is supported with the +XWin(__appmansuffix__) X server. +.PP +.SH "NETWORK CONNECTIONS" +.B __xservername__ +supports connections made using the following reliable +byte-streams: +.TP 4 +.I "Local" +On most platforms, the "Local" connection type is a UNIX-domain socket. +On some System V platforms, the "local" connection types also include +STREAMS pipes, named pipes, and some other mechanisms. +.TP 4 +.I TCP\/IP +.B __xservername__ +listens on port +.RI 6000+ n , +where +.I n +is the display number. This connection type can be disabled with the +.B \-nolisten +option (see the Xserver(1) man page for details). +.SH "ENVIRONMENT VARIABLES" +For operating systems that support local connections other than Unix +Domain sockets (SVR3 and SVR4), there is a compiled-in list specifying +the order in which local connections should be attempted. This list +can be overridden by the +.I XLOCAL +environment variable described below. If the display name indicates a +best-choice connection should be made (e.g. +.BR :0.0 ), +each connection mechanism is tried until a connection succeeds or no +more mechanisms are available. Note: for these OSs, the Unix Domain +socket connection is treated differently from the other local connection +types. To use it the connection must be made to +.BR unix:0.0 . +.PP +The +.I XLOCAL +environment variable should contain a list of one more +more of the following: +.PP +.RS 8 +.nf +NAMED +PTS +SCO +ISC +.fi +.RE +.PP +which represent SVR4 Named Streams pipe, Old-style USL Streams pipe, +SCO XSight Streams pipe, and ISC Streams pipe, respectively. You can +select a single mechanism (e.g. +.IR XLOCAL=NAMED ), +or an ordered list (e.g. \fIXLOCAL="NAMED:PTS:SCO"\fP). +his variable overrides the compiled-in defaults. For SVR4 it is +recommended that +.I NAMED +be the first preference connection. The default setting is +.IR PTS:NAMED:ISC:SCO . +.PP +To globally override the compiled-in defaults, you should define (and +export if using +.B sh +or +.BR ksh ) +.I XLOCAL +globally. If you use startx(1) or xinit(1), the definition should be +at the top of your +.I .xinitrc +file. If you use xdm(1), the definitions should be early on in the +.I __projectroot__/lib/X11/xdm/Xsession +script. +.SH OPTIONS +.B __xservername__ +supports several mechanisms for supplying/obtaining configuration and +run-time parameters: command line options, environment variables, the +__xconfigfile__(__filemansuffix__) configuration files, auto-detection, and +fallback defaults. When the same information is supplied in more than +one way, the highest precedence mechanism is used. The list of mechanisms +is ordered from highest precedence to lowest. Note that not all parameters +can be supplied via all methods. The available command line options +and environment variables (and some defaults) are described here and in +the Xserver(__appmansuffix__) manual page. Most configuration file +parameters, with their defaults, are described in the +__xconfigfile__(__filemansuffix__) manual page. Driver and module specific +configuration parameters are described in the relevant driver or module +manual page. +.PP +In addition to the normal server options described in the +Xserver(__appmansuffix__) manual page, +.B __xservername__ +accepts the following command line switches: +.TP 8 +.BI vt XX +.I XX +specifies the Virtual Terminal device number which +.B __xservername__ +will use. Without this option, +.B __xservername__ +will pick the first available Virtual Terminal that it can locate. This +option applies only to platforms that have virtual terminal support, such +as Linux, BSD, OpenSolaris, SVR3, and SVR4. +.TP +.B \-allowMouseOpenFail +Allow the server to start up even if the mouse device can't be opened +or initialised. This is equivalent to the +.B AllowMouseOpenFail +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-allowNonLocalXvidtune +Make the VidMode extension available to remote clients. This allows +the xvidtune client to connect from another host. This is equivalent +to the +.B AllowNonLocalXvidtune +__xconfigfile__(__filemansuffix__) file option. By default non-local +connections are not allowed. +.TP 8 +.BI \-bgamma " value" +Set the blue gamma correction. +.I value +must be between 0.1 and 10. +The default is 1.0. Not all drivers support this. See also the +.BR \-gamma , +.BR \-rgamma , +and +.B \-ggamma +options. +.TP 8 +.BI \-bpp " n" +No longer supported. Use +.B \-depth +to set the color depth, and use +.B \-fbbpp +if you really need to force a non-default framebuffer (hardware) pixel +format. +.TP 8 +.BI \-config " file" +Read the server configuration from +.IR file . +This option will work for any file when the server is run as root (i.e, +with real-uid 0), or for files relative to a directory in the config +search path for all other users. +.TP 8 +.BI \-configdir " directory" +Read the server configuration files from +.IR directory . +This option will work for any directory when the server is run as root +(i.e, with real-uid 0), or for directories relative to a directory in the +config directory search path for all other users. +.TP 8 +.B \-configure +When this option is specified, the +.B __xservername__ +server loads all video driver modules, probes for available hardware, +and writes out an initial __xconfigfile__(__filemansuffix__) file based on +what was detected. This option currently has some problems on some +platforms, but in most cases it is a good way to bootstrap the +configuration process. This option is only available when the server +is run as root (i.e, with real-uid 0). +.TP 8 +.BI "\-crt /dev/tty" XX +SCO only. This is the same as the +.B vt +option, and is provided for compatibility with the native SCO X server. +.TP 8 +.BI \-depth " n" +Sets the default color depth. Legal values are 1, 4, 8, 15, 16, and +24. Not all drivers support all values. +.TP 8 +.B \-disableVidMode +Disable the parts of the VidMode extension (used by the xvidtune +client) that can be used to change the video modes. This is equivalent +to the +.B DisableVidModeExtension +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-fbbpp \fIn\fP +Sets the number of framebuffer bits per pixel. You should only set this +if you're sure it's necessary; normally the server can deduce the correct +value from +.B \-depth +above. Useful if you want to run a depth 24 configuration with a 24 +bpp framebuffer rather than the (possibly default) 32 bpp framebuffer +(or vice versa). Legal values are 1, 8, 16, 24, 32. Not all drivers +support all values. +.TP 8 +.B \-flipPixels +Swap the default values for the black and white pixels. +.TP 8 +.BI \-gamma " value" +Set the gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. This value is applied +equally to the R, G and B values. Those values can be set independently +with the +.BR \-rgamma , +.BR \-bgamma , +and +.B \-ggamma +options. Not all drivers support this. +.TP 8 +.BI \-ggamma " value" +Set the green gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. Not all drivers support +this. See also the +.BR \-gamma , +.BR \-rgamma , +and +.B \-bgamma +options. +.TP 8 +.B \-ignoreABI +The +.B __xservername__ +server checks the ABI revision levels of each module that it loads. It +will normally refuse to load modules with ABI revisions that are newer +than the server's. This is because such modules might use interfaces +that the server does not have. When this option is specified, mismatches +like this are downgraded from fatal errors to warnings. This option +should be used with care. +.TP 8 +.B \-isolateDevice \fIbus\-id\fP +Restrict device resets to the device at +.IR bus\-id . +The +.I bus\-id +string has the form +.IB bustype : bus : device : function +(e.g., \(oqPCI:1:0:0\(cq). +At present, only isolation of PCI devices is supported; i.e., this option +is ignored if +.I bustype +is anything other than \(oqPCI\(cq. +.TP 8 +.B \-keeptty +Prevent the server from detaching its initial controlling terminal. +This option is only useful when debugging the server. Not all platforms +support (or can use) this option. +.TP 8 +.BI \-keyboard " keyboard-name" +Use the __xconfigfile__(__filemansuffix__) file +.B InputDevice +section called +.I keyboard-name +as the core keyboard. This option is ignored when the +.B Layout +section specifies a core keyboard. In the absence of both a Layout +section and this option, the first relevant +.B InputDevice +section is used for the core keyboard. +.TP 8 +.BI \-layout " layout-name" +Use the __xconfigfile__(__filemansuffix__) file +.B Layout +section called +.IR layout-name . +By default the first +.B Layout +section is used. +.TP 8 +.BI \-logfile " filename" +Use the file called +.I filename +as the +.B __xservername__ +server log file. The default log file is +.BI __logdir__/__xservername__. n .log +on most platforms, where +.I n +is the display number of the +.B __xservername__ +server. The default may be in a different directory on some platforms. +This option is only available when the server is run as root (i.e, with +real-uid 0). +.TP 8 +.BR \-logverbose " [\fIn\fP]" +Sets the verbosity level for information printed to the +.B __xservername__ +server log file. If the +.I n +value isn't supplied, each occurrence of this option increments the log +file verbosity level. When the +.I n +value is supplied, the log file verbosity level is set to that value. +The default log file verbosity level is 3. +.TP 8 +.BI \-modulepath " searchpath" +Set the module search path to +.IR searchpath . +.I searchpath +is a comma separated list of directories to search for +.B __xservername__ +server modules. This option is only available when the server is run +as root (i.e, with real-uid 0). +.TP 8 +.B \-nosilk +Disable Silken Mouse support. +.TP 8 +.B \-pixmap24 +Set the internal pixmap format for depth 24 pixmaps to 24 bits per pixel. +The default is usually 32 bits per pixel. There is normally little +reason to use this option. Some client applications don't like this +pixmap format, even though it is a perfectly legal format. This is +equivalent to the +.B Pixmap +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-pixmap32 +Set the internal pixmap format for depth 24 pixmaps to 32 bits per pixel. +This is usually the default. This is equivalent to the +.B Pixmap +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.BI \-pointer " pointer-name" +Use the __xconfigfile__(__filemansuffix__) file +.B InputDevice +section called +.I pointer-name +as the core pointer. This option is ignored when the +.B Layout +section specifies a core pointer. In the absence of both a Layout +section and this option, the first relevant +.B InputDevice +section is used for the core pointer. +.TP 8 +.B \-quiet +Suppress most informational messages at startup. The verbosity level +is set to zero. +.TP 8 +.BI \-rgamma " value" +Set the red gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. Not all drivers support +this. See also the +.BR \-gamma , +.BR \-bgamma , +and +.B \-ggamma +options. +.TP 8 +.BI \-screen " screen-name" +Use the __xconfigfile__(__filemansuffix__) file +.B Screen +section called +.IR screen-name . +By default the screens referenced by the default +.B Layout +section are used, or the first +.B Screen +section when there are no +.B Layout +sections. +.TP 8 +.B \-showconfig +This is the same as the +.B \-version +option, and is included for compatibility reasons. It may be removed +in a future release, so the +.B \-version +option should be used instead. +.TP 8 +.B \-showDefaultModulePath +Print out the default module path the server was compiled with. +.TP 8 +.B \-showDefaultLibPath +Print out the path libraries should be installed to. +.TP 8 +.B \-showopts +For each driver module installed, print out the list of options and their +argument types. +.TP 8 +.BI \-weight " nnn" +Set RGB weighting at 16 bpp. The default is 565. This applies only to +those drivers which support 16 bpp. +.TP 8 +.BR \-verbose " [\fIn\fP]" +Sets the verbosity level for information printed on stderr. If the +.I n +value isn't supplied, each occurrence of this option increments the +verbosity level. When the +.I n +value is supplied, the verbosity level is set to that value. The default +verbosity level is 0. +.TP 8 +.B \-version +Print out the server version, patchlevel, release date, the operating +system/platform it was built on, and whether it includes module loader +support. +.SH "KEYBOARD" +.PP +The +.B __xservername__ +server is normally configured to recognize various special combinations +of key presses that instruct the server to perform some action, rather +than just sending the key press event to a client application. These actions +depend on the XKB keymap loaded by a particular keyboard device and may or +may not be available on a given configuration. +.PP +The following key combinations are commonly part of the default XKEYBOARD +keymap. +.TP 8 +.B Ctrl+Alt+Backspace +Immediately kills the server -- no questions asked.

The current version of this automatic configuration +mechanism works in two ways. +.PP +The first is via enhancements that have made many components of the +.B __xconfigfile__ +file optional. This means that information that can be probed or +reasonably deduced doesn't need to be specified explicitly, greatly +reducing the amount of built-in configuration information that needs to +be generated at run-time. +.PP +The second is to have "safe" fallbacks for most configuration information. +This maximises the likelihood that the +.B __xservername__ +server will start up in some usable configuration even when information +about the specific hardware is not available. +.PP +The automatic configuration support for __xservername__ is work in progress. +It is currently aimed at the most popular hardware and software platforms +supported by __xservername__.

-.SH NAME
-__xconfigfile__ and __xconfigdir__ \- configuration files for
-__xservername__ X server
-.SH INTRODUCTION
-.B __xservername__
-supports several mechanisms for supplying/obtaining configuration and
-run-time parameters: command line options, environment variables, the
-__xconfigfile__ and __xconfigdir__ configuration files, auto-detection,
-and fallback defaults. When the same information is supplied in more
-than one way, the highest precedence mechanism is used. The list of
-mechanisms is ordered from highest precedence to lowest. Note that not
-all parameters can be supplied via all methods. The available command
-line options and environment variables (and some defaults) are
-described in the Xserver(__appmansuffix__) and
-__xservername__(__appmansuffix__) manual pages. Most configuration file
-parameters, with their defaults, are described below. Driver and module
-specific configuration parameters are described in the relevant driver
-or module manual page.
-.SH DESCRIPTION
-.B __xservername__
-uses a configuration file called
-.I __xconfigfile__
-and files ending in the suffix
-.I .conf
-from the directory
-.I __xconfigdir__
-for its initial setup.
-The
-.I __xconfigfile__
-configuration file is searched for in the following places when the
-server is started as a normal user:
-.PP

-.I <cmdline>
-is a relative path (with no \(lq..\(rq components) specified with the
-.B \-config
-command line option,
-.B $XORGCONFIG
-is the relative path (with no \(lq..\(rq components) specified by that
-environment variable, and
-.I <hostname>
-is the machine's hostname as reported by
-.BR gethostname (__libmansuffix__).
-.PP
-When the __xservername__ server is started by the \(lqroot\(rq user, the config file
-search locations are as follows:
-.PP
-.RS 4

-.RE
-.PP
-where
-.I <cmdline>
-is the path specified with the
-.B \-config
-command line option (which may be absolute or relative),
-.B $XORGCONFIG
-is the path specified by that
-environment variable (absolute or relative),
-.B $HOME
-is the path specified by that environment variable (usually the home
-directory), and
-.I <hostname>
-is the machine's hostname as reported by
-.BR gethostname (__libmansuffix__).
-.PP
-Additional configuration files are searched for in the following
-directories when the server is started as a normal user:
-.PP
-.RS 4
-.nf
-.IR /etc/X11/ <cmdline>
-.IR __sysconfdir__/X11/ <cmdline>
-.I /etc/X11/__xconfigdir__

-.fi
-.RE
-.PP
-where
-.I <cmdline>
-is a relative path (with no \(lq..\(rq components) specified with the
-.B \-configdir
-command line option.
-.PP
-When the __xservername__ server is started by the \(lqroot\(rq user, the
-config directory search locations are as follows:
-.PP
-.RS 4
-.nf
-<cmdline>
-.IR /etc/X11/ <cmdline>
-.IR __sysconfdir__/X11/ <cmdline>
-.I /etc/X11/__xconfigdir__

-.fi
-.RE
-.PP
-where
-.I <cmdline>
-is the path specified with the
-.B \-configdir
-command line option (which may be absolute or relative).
-.PP
-Finally, configuration files will also be searched for in directories
-reserved for system use. These are to separate configuration files from
-the vendor or 3rd party packages from those of local administration.
-These files are found in the following directories:
-.PP
-.RS 4

-sections are at the highest level.
-They bind together the input and output devices that will be used in a session.
-The input devices are described in the
-.B InputDevice
-sections.
-Output devices usually consist of multiple independent components (e.g.,
-a graphics board and a monitor).
-These multiple components are bound together in the
-.B Screen
-sections, and it is these that are referenced by the
-.B ServerLayout
-section.
-Each
-.B Screen
-section binds together a graphics board and a monitor.
-The graphics boards are described in the
-.B Device
-sections, and the monitors are described in the
-.B Monitor
-sections.
-.PP
-Config file keywords are case\-insensitive, and \(lq_\(rq characters are
-ignored.
-Most strings (including
-.B Option
-names) are also case-insensitive, and insensitive to white space and
-\(lq_\(rq characters.
-.PP
-Each config file entry usually takes up a single line in the file. They
-consist of a keyword, which is possibly followed by one or more arguments,
-with the number and types of the arguments depending on the keyword.

-.BR "Integer " "an integer number in decimal, hex or octal"
-.BR "Real " "a floating point number"
-.BR "String " "a string enclosed in double quote marks (\*q)"
-.fi
-.RE
-.PP
-Note: hex integer values must be prefixed with \(lq0x\(rq, and octal values
-with \(lq0\(rq.
-.PP
-A special keyword called
-.B Option
-may be used to provide free\-form data to various components of the server.
-The
-.B Option
-keyword takes either one or two string arguments.
-The first is the option name, and the optional second argument is the
-option value.
-Some commonly used option value types include:

-.B Options
-specified in this section (with the exception of the
-.B \*qDefaultServerLayout\*q
-.BR Option )
-may be overridden by

-Options with command line equivalents are overridden when their command
-line equivalent is used.
-The options recognised by this section are:
-.TP 7
-.BI "Option \*qDefaultServerLayout\*q \*q" layout\-id \*q
-This specifies the default
-.B ServerLayout
-section to use in the absence of the
-.B \-layout
-command line option.
-.TP 7
-.BI "Option \*qNoTrapSignals\*q \*q" boolean \*q
-This prevents the __xservername__ server from trapping a range of unexpected fatal
-signals and exiting cleanly.
-Instead, the __xservername__ server will die and drop core where the fault occurred.
-The default behaviour is for the __xservername__ server to exit cleanly, but still drop a
-core file.
-In general you never want to use this option unless you are debugging an __xservername__
-server problem and know how to deal with the consequences.
-.TP 7
-.BI "Option \*qUseSIGIO\*q \*q" boolean \*q
-This controls whether the __xservername__ server requests that events from
-input devices be reported via a SIGIO signal handler (also known as SIGPOLL
-on some platforms), or only reported via the standard select(3) loop.
-The default behaviour is platform specific. In general you do not want to
-use this option unless you are debugging the __xservername__ server, or
-working around a specific bug until it is fixed, and understand the
-consequences.
-.TP 7
-.BI "Option \*qDontVTSwitch\*q \*q" boolean \*q
-This disallows the use of the
-.BI Ctrl+Alt+F n
-sequence (where
-.RI F n
-refers to one of the numbered function keys).
-That sequence is normally used to switch to another \*qvirtual terminal\*q
-on operating systems that have this feature.
-When this option is enabled, that key sequence has no special meaning and
-is passed to clients.
-Default: off.
-.TP 7
-.BI "Option \*qDontZap\*q \*q" boolean \*q
-This disallows the use of the
-.B Terminate_Server
-XKB action (usually on Ctrl+Alt+Backspace, depending on XKB options).
-This action is normally used to terminate the __xservername__ server.
-When this option is enabled, the action has no effect.
-Default: off.
-.TP 7
-.BI "Option \*qDontZoom\*q \*q" boolean \*q
-This disallows the use of the
-.B Ctrl+Alt+Keypad\-Plus
-and
-.B Ctrl+Alt+Keypad\-Minus
-sequences.
-These sequences allows you to switch between video modes.
-When this option is enabled, those key sequences have no special meaning
-and are passed to clients.
-Default: off.
-.TP 7
-.BI "Option \*qDisableVidModeExtension\*q \*q" boolean \*q
-This disables the parts of the VidMode extension used by the xvidtune client
-that can be used to change the video modes.
-Default: the VidMode extension is enabled.
-.TP 7
-.BI "Option \*qAllowNonLocalXvidtune\*q \*q" boolean \*q
-This allows the xvidtune client (and other clients that use the VidMode
-extension) to connect from another host.
-Default: off.
-.TP 7
-.BI "Option \*qAllowMouseOpenFail\*q \*q" boolean \*q
-This tells the mousedrv(__drivermansuffix__) and vmmouse(__drivermansuffix__)

-.SH "MODULE SECTION"
-The
-.B Module
-section is used to specify which __xservername__ server modules should be loaded.
-This section is ignored when the __xservername__ server is built in static form.
-The type of modules normally loaded in this section are __xservername__ server
-extension modules.
-Most other module types are loaded automatically when they are needed via
-other mechanisms.
-The
-.B Module
-section is optional, as are all of the entries that may be specified in
-it.
-.PP
-Entries in this section may be in two forms.
-The first and most commonly used form is an entry that uses the
-.B Load
-keyword, as described here:
-.TP 7
-.BI "Load \*q" modulename \*q
-This instructs the server to load the module called
-.IR modulename .
-The module name given should be the module's standard name, not the
-module file name.
-The standard name is case\-sensitive, and does not include the \(lqlib\(rq
-prefix, or the \(lq.a\(rq, \(lq.o\(rq, or \(lq.so\(rq suffixes.
-.PP
-.RS 7
-Example: the DRI extension module can be loaded with the following entry:
-.PP
-.RS 4
-.B "Load \*qdri\*q"
-.RE
-.RE
-.TP 7
-.BI "Disable \*q" modulename \*q
-This instructs the server to not load the module called
-.IR modulename .
-Some modules are loaded by default in the server, and this overrides that
-default. If a
-.B Load
-instruction is given for the same module, it overrides the
-.B Disable
-instruction and the module is loaded. The module name given should be the
-module's standard name, not the module file name. As with the
-.B Load
-instruction, the standard name is case-sensitive, and does not include the
-"lib" prefix, or the ".a", ".o", or ".so" suffixes.
-.PP
-The second form of entry is a
-.BR SubSection,
-with the subsection name being the module name, and the contents of the
-.B SubSection
-being
-.B Options
-that are passed to the module when it is loaded.
-.PP
-Example: the extmod module (which contains a miscellaneous group of
-server extensions) can be loaded, with the XFree86\-DGA extension
-disabled by using the following entry:
-.PP
-.RS 4
-.nf
-.B "SubSection \*qextmod\*q"
-.B " Option \*qomit XFree86\-DGA\*q"
-.B EndSubSection
-.fi
-.RE
-.PP
-Modules are searched for in each directory specified in the
-.B ModulePath
-search path, and in the drivers, extensions, input, internal, and
-multimedia subdirectories of each of those directories.
-In addition to this, operating system specific subdirectories of all
-the above are searched first if they exist.
-.PP
-To see what extension modules are available, check the extensions
-subdirectory under:
-.PP

-are present, unless disabled with \*qDisable\*q entries.
-It is recommended
-that at very least the \(lqextmod\(rq extension module be loaded.
-If it isn't, some commonly used server extensions (like the SHAPE
-extension) will not be available.
-.SH "EXTENSIONS SECTION"
-The
-.B Extensions
-section is used to specify which X11 protocol extensions should be enabled
-or disabled.
-The
-.B Extensions

-it.
-.PP
-Entries in this section are listed as Option statements with the name of
-the extension as the first argument, and a boolean value as the second.
-The extension name is case\-sensitive, and matches the form shown in the output
-of \*qXorg -extension ?\*q.
-.PP
-.RS 7
-Example: the MIT-SHM extension can be disabled with the following entry:

-backend being the default backend for X servers since 1.4. It is usually not
-necessary to provide
-.B InputDevice
-sections in the xorg.conf if hotplugging is enabled.
-.PP
-If hotplugging is disabled, there will normally
-be at least two: one for the core (primary) keyboard
-and one for the core pointer.
-If either of these two is missing, a default configuration for the missing
-ones will be used. In the absence of an explicitly specified core input
-device, the first
-.B InputDevice
-marked as
-.B CorePointer
-(or
-.BR CoreKeyboard )
-is used.
-If there is no match there, the first
-.B InputDevice

-.PP
-With RandR 1.2-enabled drivers, monitor sections may be tied to specific
-outputs of the video card. Using the name of the output defined by the video
-driver plus the identifier of a monitor section, one associates a monitor
-section with an output by adding an option to the Device section in the

-(for example,
-.B Option \*qMonitor-VGA\*q \*qVGA monitor\*q

-In the absence of specific association of monitor sections to outputs, if a
-monitor section is present the server will associate it with an output to
-preserve compatibility for previous single-head configurations.

When the same information is supplied in more +than one way, the highest precedence mechanism is used. The list of +mechanisms is ordered from highest precedence to lowest. Note that not +all parameters can be supplied via all methods. The available command +line options and environment variables (and some defaults) are +described in the Xserver(__appmansuffix__) and +__xservername__(__appmansuffix__) manual pages. Most configuration file +parameters, with their defaults, are described below. Driver and module +specific configuration parameters are described in the relevant driver +or module manual page. +.SH DESCRIPTION +.B __xservername__ +uses a configuration file called +.I __xconfigfile__ +and files ending in the suffix +.I .conf +from the directory +.I __xconfigdir__ +for its initial setup. +The +.I __xconfigfile__ +configuration file is searched for in the following places when the +server is started as a normal user: +.PP +.RS 4 +.nf +.IR /etc/X11/ <cmdline> +.IR __projectroot__/etc/X11/ <cmdline> +.IB /etc/X11/ $XORGCONFIG +.IB __projectroot__/etc/X11/ $XORGCONFIG +.I /etc/X11/__xconfigfile__ +.I /etc/__xconfigfile__ +.IR __projectroot__/etc/X11/__xconfigfile__. <hostname> +.I __projectroot__/etc/X11/__xconfigfile__ +.IR __projectroot__/lib/X11/__xconfigfile__. <hostname> +.I __projectroot__/lib/X11/__xconfigfile__ +.fi +.RE +.PP +where +.I <cmdline> +is a relative path (with no \(lq..\(rq components) specified with the +.B \-config +command line option, +.B $XORGCONFIG +is the relative path (with no \(lq..\(rq components) specified by that +environment variable, and +.I <hostname> +is the machine's hostname as reported by +.BR gethostname (__libmansuffix__). +.PP +When the __xservername__ server is started by the \(lqroot\(rq user, the config file +search locations are as follows: +.PP +.RS 4 +.nf +<cmdline> +.IR /etc/X11/ <cmdline> +.IR __projectroot__/etc/X11/ <cmdline> +.B $XORGCONFIG +.IB /etc/X11/ $XORGCONFIG +.IB __projectroot__/etc/X11/ $XORGCONFIG +.I /etc/X11/__xconfigfile__ +.I /etc/__xconfigfile__ +.IR __projectroot__/etc/X11/__xconfigfile__. <hostname> +.I __projectroot__/etc/X11/__xconfigfile__ +.IR __projectroot__/lib/X11/__xconfigfile__. <hostname> +.I __projectroot__/lib/X11/__xconfigfile__ +.fi +.RE +.PP +where +.I <cmdline> +is the path specified with the +.B \-config +command line option (which may be absolute or relative), +.B $XORGCONFIG +is the path specified by that +environment variable (absolute or relative), +.B $HOME +is the path specified by that environment variable (usually the home +directory), and +.I <hostname> +is the machine's hostname as reported by +.BR gethostname (__libmansuffix__). +.PP +Additional configuration files are searched for in the following +directories when the server is started as a normal user: +.PP +.RS 4 +.nf +.IR /etc/X11/ <cmdline> +.IR __sysconfdir__/X11/ <cmdline> +.I /etc/X11/__xconfigdir__ +.I __sysconfdir__/X11/__xconfigdir__ +.fi +.RE +.PP +where +.I <cmdline> +is a relative path (with no \(lq..\(rq components) specified with the +.B \-configdir +command line option. +.PP +When the __xservername__ server is started by the \(lqroot\(rq user, the +config directory search locations are as follows: +.PP +.RS 4 +.nf +<cmdline> +.IR /etc/X11/ <cmdline> +.IR __sysconfdir__/X11/ <cmdline> +.I /etc/X11/__xconfigdir__ +.I __sysconfdir__/X11/__xconfigdir__ +.fi +.RE +.PP +where +.I <cmdline> +is the path specified with the +.B \-configdir +command line option (which may be absolute or relative). +.PP +Finally, configuration files will also be searched for in directories +reserved for system use.

-.SH NAME
-XWin \- X Server for the Cygwin environment on Microsoft Windows
-
-
-.SH SYNOPSIS
-.B XWin
-[ options ] ...
-
-
-.SH DESCRIPTION
-\fIXWin\fP is an X Server for the X Window System on the Cygwin environment
-running on Microsoft Windows.
-
-
-.SH MODES
-\fIXWin\fP can operate in 3 different modes:
-.br
-* \fISingle Window\fP: This is the default mode. Each X screen
-appears as a single \fIWindows\fP window and all X windows are contained
-within this window.
-(In X terminology, the \fIWindows\fP window contains the root window for
-the screen)
-.br
-* \fIMulti-Window\fP: In this mode \fIXWin\fP uses its own integrated
-window manager in order to handle the top-level X windows, in such a
-way that they appear as normal \fIWindows\fP windows.
-.br
-* \fIRootless\fP: In this mode the X server works in a window
-containing the whole screen but this root window (traditionally covered with an X hatch
-pattern) is hidden from view, so only top-level X windows are seen.
-
-.SH OPTIONS
-In addition to the normal server options described in the \fIXserver(1)\fP
-manual page, \fIXWin\fP accepts the following command line switches,
-\fIall\fP of which are optional:
-
-.SH OPTIONS CONTROLLING WINDOWING MODE
-Only one of these options may be specified.
-.TP 8
-.B (default)
-Windowed or rooted mode.
-Each X screen appears as a single \fIWindows\fP window and all X windows are
-contained within those windows.
-.TP 8
-.B \-multiwindow
-Each top-level X window appears in its own \fIWindows\fP window.
-Also start the integrated \fIWindows\fP-based window manager.
-.TP 8
-.B \-rootless
-Run the server in rootless mode.
-The X server works on a window covering the whole screen but the root window
-is hidden from view.
-.TP 8
-.B \-mwextwm
-Experimental.
-The mode combines \fB\-rootless\fP mode drawing with native \fIWindows\fP
-window frames managed by the experimental external window manager \fIxwinwm\fP.
-.PP
-\fBNOTE:\fP \fI-multiwindow\fP mode uses its own internal window manager.
-All other modes require an external window manager in order to move, resize, and perform other
-operations on the individual X windows.
-
-.SH OPTIONS FOR SPECIFYING X SCREENS
-An X display may be composed of multiple screens.
-The default behaviour is to create a single screen 0 that is roughly the
-size of useful area of the primary monitor (allowing for any window
-decorations and the task-bar).
-
-Screen specific parameters, such as \fB\-fullscreen\fP, can be applied as a
-default to all screens by placing those screen specific parameters
-before any \fB\-screen\fP parameter. Screen specific parameters placed after
-the first \fB\-screen\fP parameter will apply only to the immediately
-preceeding \fB\-screen\fP parameter.
-.TP 8
-.B \-[no]multimonitors or \-[no]multiplemonitors
-Create a screen 0 that covers all monitors [the primary monitor] on a system with
-multiple monitors.
-This option is currently enabled by default in \fB\-multiwindow\fP mode.
-.TP 8
-.B "\-screen \fIscreen_number\fP [\fIW\fP \fIH\fP [\fIX\fP \fIY\fP] | [[\fIW\fPx\fIH\fP[+\fIX\fP+\fIY\fP]][@\fIM\fP]] ] "
-Create screen number
-.I screen_number
-and optionally specify it's
-.I height,
-.I width
-and
-.I initial position.
-Additionally a
-.I
-monitor number
-(which count from 1) can be specified to place the screen on,
-at which point, all coordinates become relative to that monitor.
-Screen numbers must be contiguous starting from zero and cannot be duplicated.
-
-Examples:
-
-.I " -screen 0 @1 ; on 1st monitor using its full resolution (the default)"
-
-.I " -screen 0 800x600+100+100@2 ; on 2nd monitor offset 100,100 size 800x600"
-
-.I " -screen 0 1024x768@3 ; on 3rd monitor size 1024x768"
-
-.SH OPTIONS CONTROLLING THE APPEARANCE OF THE X SCREEN WINDOWS
-These parameters only apply to windowed mode screens i.e. not
-in \fB-multwindow\fP or \fB-rootless\fP mode
-.TP 8
-.B "\-fullscreen"
-The X server window takes the full screen, covering completely the
-\fIWindows\fP desktop.
-.TP 8
-.B \-nodecoration
-Do not give the Cygwin/X window a \fIWindows\fP window border, title bar,
-etc.
-This parameter is ignored when the \fB\-fullscreen\fP parameter is specified.
-.TP 8
-.B \-scrollbars
-In windowed mode, allow screens bigger than the \fIWindows\fP desktop.
-Moreover, if the window has decorations, one can now resize it.
-This parameter is ignored when the \fB\-fullscreen\fP parameter is specified.
-
-
-.SH OPTIONS CONTROLLING WINDOWS INTEGRATION
-.TP 8
-.B \-[no]clipboard
-Enables [disables] the integration between the Cygwin/X clipboard and
-\fIWindows\fP clipboard. The default is enabled.
-.TP 8
-.B "\-emulate3buttons [\fItimeout\fP]"
-Emulate a three button mouse; pressing both buttons within
-.I timeout
-milliseconds causes an emulated middle button press. The default
-.I timeout
-is 50 milliseconds. Note that most mice with scroll wheel have middle
-button functionality, usually you will need this option only if you have
-a two button mouse without scroll wheel.
-.TP 8
-.B \-[no]keyhook
-Enable [disable] a low-level keyboard hook for catching
-special keypresses like Menu and Alt+Tab and passing them to the X
-Server instead of letting \fIWindows\fP handle them.
-.TP 8
-.B \-lesspointer
-Normally the \fIWindows\fP mouse cursor is hidden when the mouse is
-over an active Cygwin/X window. This option causes the mouse cursor
-also to be hidden when it is over an inactive Cygwin/X window. This
-prevents the \fIWindows\fP mouse cursor from being drawn on top of the X
-cursor.
-This parameter has no effect unless \fB-swcursor\fP is also specified.
-.TP 8
-.B \-swcursor
-Disable the usage of the \fIWindows\fP cursor and use the X11 software cursor instead.
-.TP 8
-.B \-[no]trayicon
-Do not create a tray icon. Default is to create one
-icon per screen. You can globally disable tray icons with
-\fB\-notrayicon\fP, then enable it for specific screens with
-\fB\-trayicon\fP for those screens.
-.TP 8
-.B \-nounicodeclipboard
-Do not use Unicode clipboard even if on a NT-based platform.
-.TP 8
-.B \-[no]unixkill
-Enable or disable the \fICtrl-Alt-Backspace\fP key combination as a
-signal to exit the X Server. The \fICtrl-Alt-Backspace\fP key combination
-is disabled by default.
-.TP 8
-.B \-[no]winkill
-Enable or disable the \fIAlt-F4\fP key combination as a signal to exit the
-X Server.
-The \fIAlt-F4\fP key combination is enabled by default.
-
-.SH DRAWING ENGINE OPTIONS
-.TP 8
-.B "\-clipupdates \fInum_boxes\fP"
-Specify an optional threshold, above which the regions in a shadow
-update operation will be collected into a GDI clipping region. The
-clipping region is then used to do a single bit block transfer that is
-constrained to the updated area by the clipping region. There is some
-overhead involved in creating, installing, destroying, and removing
-the clipping region, thus there may not be much benefit for a small
-number of boxes (less than 10). It is even possible that this
-functionality does not provide a benefit at any number of boxes; we
-can only determine the usefulness of this feature through testing.
-This option probably has limited effect on current \fIWindows\fP versions
-as they already perform GDI batching.
-This parameter works in conjunction with engines 1, 2, and 4 (Shadow
-GDI, Shadow DirectDraw, and Shadow DirectDraw Non-Locking,
-respectively).
-.TP 8
-.B "\-engine \fIengine_type_id\fP"
-This option, which is intended for Cygwin/X developers,
-overrides the server's automatically selected engine type. This
-parameter will be ignored if the specified engine type is not
-supported on the current system. The supported engine type ids are 1
-- Shadow GDI, 2 - Shadow DirectDraw, and 4 - Shadow DirectDraw Non-Locking.
-Additionally, there are engines with type ids
-8 - Primary DirectDraw (obsolete) and 16 - Native GDI (experimental and barely functional).
-Default behavior is to determine the engine with optimum performance that
-supports the specified depth and window configuration.
-
-.SH FULLSCREEN OPTIONS
-.TP 8
-.B "\-depth \fIdepth\fP"
-Specify the color depth, in bits per pixel, to use when running in
-fullscreen with a DirectDraw engine. This parameter is ignored if
-\fB\-fullscreen\fP is not specified.
-.TP 8
-.B "\-refresh \fIrate_in_Hz\fP"
-Specify an optional refresh rate to use when running in
-fullscreen with a DirectDraw engine. This parameter is ignored if
-\fB\-fullscreen\fP is not specified.
-
-.SH MISCELLANEOUS OPTIONS
-See also the normal server options described in the \fIXserver(1)\fP
-manual page
-
-.TP 8
-.B \-help
-Write a help text listing supported command line options and their description to the console.
-.TP 8
-.B \-ignoreinput
-Ignore keyboard and mouse input. This is usually only used for testing
-and debugging purposes.
-.TP 8
-.B "\-logfile \fIfilename\fP"
-Change the server log file from the default of \fI
-__logdir__/XWin.n.log\fP,
-where \fIn\fP is the display number of the XWin server, to \fIfilename\fP.
-.TP 8
-.B "\-logverbose \fIlevel\fP"
-Control the degree of verbosity of the log messages with the integer
-parameter \fIlevel\fP. For \fIlevel\fP=0 only fatal errors are
-reported, for \fIlevel\fP=1 simple information about
-configuration is also given, for \fIlevel\fP=2 (default)
-additional runtime information is recorded
-and for \fIlevel\fP=3 detailed log
-information (including trace and debug output) is produced. Bigger
-values will yield a still more detailed debug output.
-.TP 8
-.B \-silent-dup-error
-If another instance of \fIXWin\fP with the same display number is found running,
-exit silently and don't display any error message.
-.TP 8
-.B "\-xkblayout \fIlayout\fP"
-.TP 8
-.B "\-xkbmodel \fImodel\fP"
-.TP 8
-.B "\-xkboptions \fIoption\fP"
-.TP 8
-.B "\-xkbrules \fIrule\fP"
-.TP 8
-.B "\-xkbvariant \fIvariant\fp"
-These options configure the xkeyboard extension to load
-a particular keyboard map as the X server starts. The behavior is similar
-to the \fIsetxkbmap\fP program. The layout data is located at \fI
-__datadir__/X11/xkb/\fP. Additional information is found in the
-README files therein and in the man page of \fIsetxkbmap\fP. For example
-in order to load a German layout for a pc105 keyboard one uses
-the options:
-.br
-.I " \-xkblayout de \-xkbmodel pc105"
-
-Alternatively one may use the \fIsetxkbmap\fP program after \fIXWin\fP is
-running.
-
-The default is to select a configuration matching your current layout as
-reported by \fIWindows\fP, if known, or the default X server configuration
-if no matching keyboard configuration was found.
-
-.SH UNDOCUMENTED OPTIONS
-These options are undocumented. Do not use them.

+.TH XWIN 1 __vendorversion__ +.SH NAME +XWin \- X Server for the Cygwin environment on Microsoft Windows + + +.SH SYNOPSIS +.B XWin +[ options ] ... + + +.SH DESCRIPTION +\fIXWin\fP is an X Server for the X Window System on the Cygwin environment +running on Microsoft Windows. + + +.SH MODES +\fIXWin\fP can operate in 3 different modes: +.br +* \fISingle Window\fP: This is the default mode. Each X screen +appears as a single \fIWindows\fP window and all X windows are contained +within this window. +(In X terminology, the \fIWindows\fP window contains the root window for +the screen) +.br +* \fIMulti-Window\fP: In this mode \fIXWin\fP uses its own integrated +window manager in order to handle the top-level X windows, in such a +way that they appear as normal \fIWindows\fP windows. +.br +* \fIRootless\fP: In this mode the X server works in a window +containing the whole screen but this root window (traditionally covered with an X hatch +pattern) is hidden from view, so only top-level X windows are seen. + +.SH OPTIONS +In addition to the normal server options described in the \fIXserver(1)\fP +manual page, \fIXWin\fP accepts the following command line switches, +\fIall\fP of which are optional: + +.SH OPTIONS CONTROLLING WINDOWING MODE +Only one of these options may be specified. +.TP 8 +.B (default) +Windowed or rooted mode. +Each X screen appears as a single \fIWindows\fP window and all X windows are +contained within those windows. +.TP 8 +.B \-multiwindow +Each top-level X window appears in its own \fIWindows\fP window. +Also start the integrated \fIWindows\fP-based window manager. +.TP 8 +.B \-rootless +Run the server in rootless mode. +The X server works on a window covering the whole screen but the root window +is hidden from view. +.TP 8 +.B \-mwextwm +Experimental. +The mode combines \fB\-rootless\fP mode drawing with native \fIWindows\fP +window frames managed by the experimental external window manager \fIxwinwm\fP. +.PP +\fBNOTE:\fP \fI-multiwindow\fP mode uses its own internal window manager. +All other modes require an external window manager in order to move, resize, and perform other +operations on the individual X windows. + +.SH OPTIONS FOR SPECIFYING X SCREENS +An X display may be composed of multiple screens. +The default behaviour is to create a single screen 0 that is roughly the +size of useful area of the primary monitor (allowing for any window +decorations and the task-bar). + +Screen specific parameters, such as \fB\-fullscreen\fP, can be applied as a +default to all screens by placing those screen specific parameters +before any \fB\-screen\fP parameter. Screen specific parameters placed after +the first \fB\-screen\fP parameter will apply only to the immediately +preceeding \fB\-screen\fP parameter. +.TP 8 +.B \-[no]multimonitors or \-[no]multiplemonitors +Create a screen 0 that covers all monitors [the primary monitor] on a system with +multiple monitors. +This option is currently enabled by default in \fB\-multiwindow\fP mode. +.TP 8 +.B "\-screen \fIscreen_number\fP [\fIW\fP \fIH\fP [\fIX\fP \fIY\fP] | [[\fIW\fPx\fIH\fP[+\fIX\fP+\fIY\fP]][@\fIM\fP]] ] " +Create screen number +.I screen_number +and optionally specify it's +.I height, +.I width +and +.I initial position. +Additionally a +.I +monitor number +(which count from 1) can be specified to place the screen on, +at which point, all coordinates become relative to that monitor. +Screen numbers must be contiguous starting from zero and cannot be duplicated. + +Examples: + +.I " -screen 0 @1 ; on 1st monitor using its full resolution (the default)" + +.I " -screen 0 800x600+100+100@2 ; on 2nd monitor offset 100,100 size 800x600" + +.I " -screen 0 1024x768@3 ; on 3rd monitor size 1024x768" + +.SH OPTIONS CONTROLLING THE APPEARANCE OF THE X SCREEN WINDOWS +These parameters only apply to windowed mode screens i.e. not +in \fB-multwindow\fP or \fB-rootless\fP mode +.TP 8 +.B "\-fullscreen" +The X server window takes the full screen, covering completely the +\fIWindows\fP desktop. +.TP 8 +.B \-nodecoration +Do not give the Cygwin/X window a \fIWindows\fP window border, title bar, +etc. +This parameter is ignored when the \fB\-fullscreen\fP parameter is specified. +.TP 8 +.B \-scrollbars +In windowed mode, allow screens bigger than the \fIWindows\fP desktop. +Moreover, if the window has decorations, one can now resize it. +This parameter is ignored when the \fB\-fullscreen\fP parameter is specified. + + +.SH OPTIONS CONTROLLING WINDOWS INTEGRATION +.TP 8 +.B \-[no]clipboard +Enables [disables] the integration between the Cygwin/X clipboard and +\fIWindows\fP clipboard. The default is enabled. +.TP 8 +.B "\-emulate3buttons [\fItimeout\fP]" +Emulate a three button mouse; pressing both buttons within +.I timeout +milliseconds causes an emulated middle button press. The default +.I timeout +is 50 milliseconds. Note that most mice with scroll wheel have middle +button functionality, usually you will need this option only if you have +a two button mouse without scroll wheel. +.TP 8 +.B \-[no]keyhook +Enable [disable] a low-level keyboard hook for catching +special keypresses like Menu and Alt+Tab and passing them to the X +Server instead of letting \fIWindows\fP handle them. +.TP 8 +.B \-lesspointer +Normally the \fIWindows\fP mouse cursor is hidden when the mouse is +over an active Cygwin/X window. This option causes the mouse cursor +also to be hidden when it is over an inactive Cygwin/X window. This +prevents the \fIWindows\fP mouse cursor from being drawn on top of the X +cursor. +This parameter has no effect unless \fB-swcursor\fP is also specified. +.TP 8 +.B \-swcursor +Disable the usage of the \fIWindows\fP cursor and use the X11 software cursor instead. +.TP 8 +.B \-[no]trayicon +Do not create a tray icon. Default is to create one +icon per screen. You can globally disable tray icons with +\fB\-notrayicon\fP, then enable it for specific screens with +\fB\-trayicon\fP for those screens. +.TP 8 +.B \-nounicodeclipboard +Do not use Unicode clipboard even if on a NT-based platform. +.TP 8 +.B \-[no]unixkill +Enable or disable the \fICtrl-Alt-Backspace\fP key combination as a +signal to exit the X Server. The \fICtrl-Alt-Backspace\fP key combination +is disabled by default. +.TP 8 +.B \-[no]winkill +Enable or disable the \fIAlt-F4\fP key combination as a signal to exit the +X Server. +The \fIAlt-F4\fP key combination is enabled by default. + +.SH DRAWING ENGINE OPTIONS +.TP 8 +.B "\-clipupdates \fInum_boxes\fP" +Specify an optional threshold, above which the regions in a shadow +update operation will be collected into a GDI clipping region. The +clipping region is then used to do a single bit block transfer that is +constrained to the updated area by the clipping region. There is some +overhead involved in creating, installing, destroying, and removing +the clipping region, thus there may not be much benefit for a small +number of boxes (less than 10). It is even possible that this +functionality does not provide a benefit at any number of boxes; we +can only determine the usefulness of this feature through testing. +This option probably has limited effect on current \fIWindows\fP versions +as they already perform GDI batching. +This parameter works in conjunction with engines 1, 2, and 4 (Shadow +GDI, Shadow DirectDraw, and Shadow DirectDraw Non-Locking, +respectively). +.TP 8 +.B "\-engine \fIengine_type_id\fP" +This option, which is intended for Cygwin/X developers, +overrides the server's automatically selected engine type. This +parameter will be ignored if the specified engine type is not +supported on the current system. The supported engine type ids are 1 +- Shadow GDI, 2 - Shadow DirectDraw, and 4 - Shadow DirectDraw Non-Locking. +Additionally, there are engines with type ids +8 - Primary DirectDraw (obsolete) and 16 - Native GDI (experimental and barely functional). +Default behavior is to determine the engine with optimum performance that +supports the specified depth and window configuration. + +.SH FULLSCREEN OPTIONS +.TP 8 +.B "\-depth \fIdepth\fP" +Specify the color depth, in bits per pixel, to use when running in +fullscreen with a DirectDraw engine. This parameter is ignored if +\fB\-fullscreen\fP is not specified. +.TP 8 +.B "\-refresh \fIrate_in_Hz\fP" +Specify an optional refresh rate to use when running in +fullscreen with a DirectDraw engine. This parameter is ignored if +\fB\-fullscreen\fP is not specified. + +.SH MISCELLANEOUS OPTIONS +See also the normal server options described in the \fIXserver(1)\fP +manual page + +.TP 8 +.B \-help +Write a help text listing supported command line options and their description to the console. +.TP 8 +.B \-ignoreinput +Ignore keyboard and mouse input. This is usually only used for testing +and debugging purposes. +.TP 8 +.B "\-logfile \fIfilename\fP" +Change the server log file from the default of \fI +__logdir__/XWin.n.log\fP, +where \fIn\fP is the display number of the XWin server, to \fIfilename\fP. +.TP 8 +.B "\-logverbose \fIlevel\fP" +Control the degree of verbosity of the log messages with the integer +parameter \fIlevel\fP. For \fIlevel\fP=0 only fatal errors are +reported, for \fIlevel\fP=1 simple information about +configuration is also given, for \fIlevel\fP=2 (default) +additional runtime information is recorded +and for \fIlevel\fP=3 detailed log +information (including trace and debug output) is produced. Bigger +values will yield a still more detailed debug output. +.TP 8 +.B \-silent-dup-error +If another instance of \fIXWin\fP with the same display number is found running, +exit silently and don't display any error message. +.TP 8 +.B "\-xkblayout \fIlayout\fP" +.TP 8 +.B "\-xkbmodel \fImodel\fP" +.TP 8 +.B "\-xkboptions \fIoption\fP" +.TP 8 +.B "\-xkbrules \fIrule\fP" +.TP 8 +.B "\-xkbvariant \fIvariant\fp" +These options configure the xkeyboard extension to load +a particular keyboard map as the X server starts. The behavior is similar +to the \fIsetxkbmap\fP program. The layout data is located at \fI +__datadir__/X11/xkb/\fP. Additional information is found in the +README files therein and in the man page of \fIsetxkbmap\fP. For example +in order to load a German layout for a pc105 keyboard one uses +the options: +.br +.I " \-xkblayout de \-xkbmodel pc105" + +Alternatively one may use the \fIsetxkbmap\fP program after \fIXWin\fP is +running. + +The default is to select a configuration matching your current layout as +reported by \fIWindows\fP, if known, or the default X server configuration +if no matching keyboard configuration was found. + +.SH UNDOCUMENTED OPTIONS +These options are undocumented. Do not use them. + +.TP 8 +.B \-emulatepseudo +Create a depth 8 PseudoColor visual when running in depths 15, 16, 24, +or 32, collectively known as TrueColor depths. +Color map manipulation is not supported, so the PseudoColor visual will +not have the correct colors. +This option is intended to allow applications which only work with a depth 8 +visual to operate in TrueColor modes. +.TP 8 +.B \-internalwm +Run the internal window manager. + +.SH LOG FILE +As it runs \fIXWin\fP writes messages indicating the most relevant events +to the console +from which it was called and to a log file that by default is located at \fI +__logdir__/XWin.0.log\fP.
